I purchased the Strontium Nitro 64GB Class10 UHS1 MicroSDXC Card as a bundle along with a SGS4 GT-I9500 and Flipkart shaved off 20% of the retail price of the card straight away. In other words, I got an unbeatable price!

I received the card only yesterday and I haven't used it enough to test the performance thoroughly. I will endeavour to update this when I have a detailed performance review ready.

Some things to note, though:- This is a MicroSDXC (Secure Digital Xtend...

I have been using the product for a month now. It works great. Read and write speeds are upto the mark. The default package form the company contains : 1 Memory Card, 1 SD Adapter, 1 Mini Pendrive Type Card reader (This is a unique product it coverts your card into a mini pen drive.
